Here's what most homeowners don't realize about garage door repair: a door that won't open or appears broken often has a simple fix you can verify yourself in under five minutes. I've responded to hundreds of service calls in Plaistow and surrounding areas where the problem wasn't mechanical failure at all. It was a dead battery, a tripped safety sensor, or a disconnected opener. Knowing how to troubleshoot saves you money, time, and the frustration of waiting for technicians when your garage door is stuck.
Before you assume your garage door opener is broken, verify the basics. Walk to your garage door opener unit (usually mounted on the ceiling). Is the light on? Is there power to the outlet? Unplug it for five seconds, then plug it back in. If the unit still has no light, your breaker may have tripped. Check your electrical panel and reset it if needed.
Next, replace the batteries in your remote control. Sounds obvious, but dead batteries cause roughly 20 percent of the "not working" calls we receive. Use fresh alkaline batteries, not old ones from a drawer. If the remote still doesn't work after a battery swap, try using the wall button inside your garage. If that works, the remote is the culprit, not the opener.
Modern garage door openers have two photoelectric sensors near the bottom of each track. These sensors prevent the door from closing if something blocks the path. When they're misaligned or dirty, the door won't close properly. Here's what to check:
Look at both sensors. Are they pointing directly at each other? Dust, spider webs, or a slight bump can knock them out of alignment. Use a soft cloth to clean the lens on each sensor. If the door still won't close, try gently realigning them so they face each other perfectly. You'll often see a small LED light on each sensor when they're communicating correctly. If one sensor has no light, it may be damaged and need replacement.
This single issue causes more "stuck" garage doors than any spring or cable problem. Before you call for same-day garage door repair, spend two minutes cleaning and checking alignment.

Walk around your garage door slowly. Are there dents, gaps, or sections that look bent? Check the tracks on both sides. Do they have debris, rust, or visible damage? A bent track can prevent smooth operation and cause the door to stick mid-cycle.
Look at the bottom seal and weatherstripping. If it's torn or missing, water and debris can accumulate in the track. This won't necessarily break your door, but it creates friction. Clean out any visible dirt or ice buildup, especially important during New England winters when ice can jam the entire mechanism.
If you see a bent panel or damaged track, stop here. That's a job for trained technicians. Trying to force a bent track straight can damage the cable or opener. Our team at Plaistow Garage Doors handles these structural repairs safely.
If your opener isn't responding but the door itself seems okay, disconnect the opener and try lifting the door by hand. First, pull the emergency release cord (usually a red rope hanging from the trolley). The door should lift smoothly with light pressure. If it's extremely heavy or won't move, your springs may be broken. If it lifts easily, the problem is likely the opener, not the door mechanism.
Never attempt to repair or adjust garage door springs yourself. They're under tremendous tension and cause serious injuries every year. If manual operation reveals a spring issue, learn when to replace your garage door opener and get professional help immediately.
If you've completed these checks and the door still won't open or is stuck, it's time to call. You've done the troubleshooting that saves money and identifies what's actually wrong. Our technicians can diagnose the real issue and provide an accurate estimate for repair cost.

Why won't my garage door open even though the opener sounds like it's running? The opener motor may be engaging, but if the door doesn't move, the cable is likely broken, the spring has failed, or the trolley has disconnected. These require professional repair and shouldn't be forced.
Can I fix misaligned safety sensors myself? Yes. Gently loosen the sensor bracket and rotate it until the LED light is steady on both units. If the light still won't turn on after cleaning and realigning, the sensor itself is damaged and needs replacement.
How often should I clean my garage door tracks? Inspect tracks monthly and clean them when you notice debris, rust, or ice buildup. Regular maintenance prevents sticking and extends the life of your rollers and cables by several years.
What does it mean if my garage door opens but won't close? Usually a safety sensor issue. Check alignment and cleanliness first. If the sensor is fine, the door may be hitting something, or the opener limit switch needs adjustment. Call for service if manual testing shows the door is extremely heavy.
Is a broken garage door cable an emergency? Yes. A broken cable means the door can fall suddenly and cause serious injury or property damage. Don't attempt to operate it. Contact us immediately for emergency repair service.
